The MIT license applies to the code in this repository, unless another license is indicated in a specific file of folder.

Getting started

Download the code. Build with Visual Studio (see https://visualstudio.microsoft.com/vs/community/). The VS build process creates an executable called farmsim.exe . A set of example input files for farmsim is located in data/hoge_born. Move to data/hoge_born/ and call make_cartesian.bat, this converts the .geojson files (WGS84) to a Cartesian coordinate system (in this case, the national Dutch system). Then you can run the model by calling farmsim.exe, for example by moving to data/hoge_born/output/ and calling go.bat .

Running the API

dotnet run --project farmsim.Api/farmsim.Api.csproj
